Detailed Description

Buffer input stream.

Constructor & Destructor Documentation

BufferInputStream()

gf::BufferInputStream::BufferInputStream

(

std::vector< uint8_t > *

bytes

)

Constructor.

Parameters

bytes

The supplied external bytes to be read

Member Function Documentation

getBytes()

std::vector<uint8_t>* gf::BufferInputStream::getBytes ( )

inline

Get the underlying bytes.

isFinished()

virtual bool gf::BufferInputStream::isFinished ( )

overridevirtual

Tell if the stream is at the end.

Returns

A boolean indicating the end of the stream

Implements gf::InputStream.

read()

virtual std::size_t gf::BufferInputStream::read ( BufferRef< uint8_t >  buffer )

overridevirtual

Read data from the stream.

After reading, the stream's reading position must be advanced by the amount of bytes read.

Parameters

buffer

The buffer where to copy the read data

Returns

The number of bytes actually read

Implements gf::InputStream.

seek()

virtual void gf::BufferInputStream::seek ( std::ptrdiff_t  position )

overridevirtual

Change the current reading position.

Parameters

position

The position to seek to, from the beginning

Implements gf::InputStream.

skip()

virtual void gf::BufferInputStream::skip ( std::ptrdiff_t  position )

overridevirtual

Change the current reading position.

Parameters

position

The position to seek to, from the current position

Implements gf::InputStream.
